They were headed for Saada province, according to Iranian media. Separately, UNICEF director for Yeman Julien Harneis said aid it's been able to deliver "cannot replace the needs of 26 million people who have been cut off from a regular supply of commercial imports of food and fuel."

"Hundreds of adults and children have already died during this conflict, many of whom could have been saved had we got supplies to them on time."

"We need to do everything we can to prevent any more of these unnecessary deaths."

"(A) diplomatic process based on a broad inter-Yemeni dialogue and relevant resolutions of the UN Security Council and the previous agreements between the Yemeni political forces are the only real chance to stop the bloodshed and to achieve lasting settlement of the Yemen conflict," Russia's MFA stressed.

"It is important to carry on the search for ways of a lasting political settlement in Yemen based on the interests of all citizens without exception and independence, sovereignty and territorial integrity of this friendly country."

"Together with other members of the international community, Russia will continue its energetic assistance in the convocation of an international forum to promote the peace process in Yemen under the UN aegis," its MFA stressed.

Obama didn't wage war on Yemen to quit. A previous article said he wants it bombed back to the 19th century.

He wants extreme pain and suffering inflicted - to force unconditional Houth surrender, to regain control over a former client state and send a message to other independent governments their turn awaits.

On May 20, a statement issued by Ban Ki-moon's spokesman said:

He announced "inclusive consultations" on Yemen aimed at achieving a Yemeni-led political transition process - code language for regime change, reinstating illegitimate US-approved figures to power.

Talks are scheduled for May 28 in Geneva. "The secretary-general urges all the participants to engage in these United Nations consultations in good faith and without preconditions," his spokesman said.

It's unclear who intends coming or what can be accomplished. Most Yemenis reject illegitimate US-imposed Hadi governance.
